    摘要: A signal transmission cable (10) having a conductor portion for transmitting signals and an insulator sheath (14) covering the conductor portion, and a high loss magnetic film (15) [is] formed on at least one part of the outer surface of the insulator sheath. The high loss magnetic film has the maximum complex permeability &mgr;″max in a frequency range of 0.1-10 gigahertz (GHz). An example of a magnetic composition of the high loss magnetic film is a M-X-Y magnetic composition wherein M is a metallic magnetic material selected from among Fe, Co, and/or Ni, X is an element or elements other than M and Y, and Y is F, N, and/or O, the M-X-Y magnetic composition having a sufficient concentration of M in the composition so that the M-X-Y magnetic compostion has a saturation magnetization of 35-80% of that of the metallic magnetic material M alone.

The maximum value &mgr;″max of an imaginary part &mgr;″, which is an imaginary number component of a complex permeability of the magnetic loss material, exists within a frequency range from 100 MHz to 10 GHz. A relative bandwidth bwr is not greater than 200% where the relative bandwidth bwr is obtained by extracting a frequency bandwidth between two frequencies at which the value of &mgr;″ is 50% of the maximum &mgr;″max and normalizing the frequency bandwidth at the center frequency thereof.
